E36General discussion and technical help for (E36) 1992-1999 3 series cars. 318, 323, 325, 328.
^^^I agree. I've been experiencing much better throttle response since I installed it. But I think it's because my old stock catback was so old that it became more restrictive. If anything, it may have simply brought back the performance that was originally there when the car was a little younger. But I guess people often confuse that and think they actually got a performance boost. The M3 catback definitely wasn't designed for the 325, in fact it may too free flowing. It's probably better suited for the 328 as a mod. But it was the choice I made, rather than pay more bucks for an OEM replacement.
I just tried to replace my stock muffler hangers with the M3 version. NOT HAPPENING. For anyone considering this, the chassis mounting bolts are too short and don't allow the nuts to go over the thicker mounting flange of the M3 hangers. The tip of the bolt doesn't even protrude from the surface of the flange hole. I'll have to figure something out . . I think the bolts are tack welded to the chassis; I don't have time right now to take the trunk apart to find out. If anyone knows, holla back. But for now I just put the old stock hangers back in . . . what a waste of time, oh well.
So here we go . . I had to mod the trunk in order to get those M3 muffler hangers installed. I had to grind off the old studs with a bandfile, and I replaced them with 5/16-18 x 1.5" bolts (the 4 white arrows). The blue arrows are what the old studs looked like:
And here's one of the new hangers installed, you can see the new bolt:
Just thought I'd share this for anyone out there who's thinking of using the M3 hangers.
